Question
How are the earth's principal biological systems being depleted?
Advertisements
Solution
According to Mr. Lester R. Brown, there are four principal biological systems of the earth. These systems are fisheries, forests, grasslands, and croplands. However, due to the increasing demand for human beings to such an ‘unsustainable’ extent, the productivity of these systems is being hampered. The excessive demand results in deterioration and depletion of these resources. A country where protein is consumed on a large scale, over-fishing is common, which leads to the collapse of fisheries in that area. Grasslands have been turned into deserts and the production of crops is decreasing. The forests are destroyed in large proportions to obtain firewood. The depletion of tropical forests has also led to the extinction of several species.
